For executing a query a schema, you can directly call the execute method on it.

schema = graphene.Schema(...)
result = schema.execute('{ name }')

result represents he result of execution. result.data is the result of executing the query, result.errors is None if no errors occurred, and is a non-empty list if an error occurred.


You can pass context to a query via context_value.

class Query(graphene.ObjectType):
    name = graphene.String()

    def resolve_name(self, args, context, info):
        return context.get('name')

schema = graphene.Schema(Query)
result = schema.execute('{ name }', context_value={'name': 'Syrus'})
